Resumen
A wavelength-switchable L-band erbium-doped fiber laser (EDFL) assisted by an artificially
controlled backscattering (ACB) fiber reflector is here presented. This random reflector was inscribed
by femtosecond (fs) laser direct writing on the axial axis of a multimode fiber with 50 lm core and 125 lm cladding with a length of 17 mm. This microstructure was placed inside a surgical syringe to be ...

A wavelength-switchable L-band erbium-doped fiber laser (EDFL) assisted by an artificially
controlled backscattering (ACB) fiber reflector is here presented. This random reflector was inscribed
by femtosecond (fs) laser direct writing on the axial axis of a multimode fiber with 50 lm core and 125 lm cladding with a length of 17 mm. This microstructure was placed inside a surgical syringe to be positioned in the
center of a high-precision rotation mount to accurately control its angle of rotation. Only by rotating this
mount, three different output spectra were obtained: a single wavelength lasing centered at 1574.75 nm, a dual
wavelength lasing centered at 1574.75 nm and 1575.75 nm, and a single wavelength lasing centered
at 1575.5 nm. All of them showed an optical signal-to-noise ratio (OSNR) of around 60 dB when pumped at
300 mW [--]
